我正在尝试使用 react-router-dom
和 react hooks
对每次路由更改的用户进行身份验证。这个想法是,每次用户导航到路由时,系统都会进行 api 调用并对用户进行身份验证。我需要实现这一点,因为我使用 react-redux
,并且在每个窗口重新加载时,redux 状态不会持久化。所以我需要将isLoggedNow
道具设置为再次true
:
const PrivateRoute = ({
component: Component,
checkOnEachRoute: checkReq,
isUserLogged,
...rest
}) => {
const [isLoggedNow, setLogged] = useState(isUserLogged);
useEffect(
() => {
const fetchStatus = async () => {
try {
await selectisUserLogged();
setLogged(true);
} catch (error) {
console.log(error);
}
};
fetchStatus();
},
[isUserLogged],
);
return (
<Route
{...rest}
render={props =>
isLoggedNow ? (
<div>
<Component {...props} />
</div>
) : (
<Redirect
to={{
pathname: '/login',
}}
/>
)
}
/>
);
};
然后我会像这样使用上面的PrivateRoute
:
function App(props) {
return (
<div>
<Switch location={props.location}>
<Route exact path="/login" component={Login} />
<PrivateRoute exact path="/sidebar" component={Sidebar} />
</Switch>
</div>
);
}
首先isUserLogged
true
,但是重新加载窗口后,我收到错误Warning: Can't perform a React state update on an unmounted component.
那么我该如何实现这一点,因此在每次窗口重新加载时我都会对用户进行身份验证?我正在寻找某种componentWillMount
.
像这样的东西有效(其中isUserLogged
是来自 redux 的道具(:
function PrivateRoute({ component: Component, isUserLogged, ...rest }) {
const [isLoading, setLoading] = useState(true);
const [isAuthenticated, setAuth] = useState(false);
useEffect(() => {
const fetchLogged = async () => {
try {
setLoading(true);
const url = new URL(fetchUrl);
const fetchedUrl = await fetchApi(url);
setAuth(fetchedUrl.body.isAllowed);
setLoading(false);
} catch (error) {
setLoading(false);
}
};
fetchLogged();
}, []);
return (
<Route
{...rest}
render={props =>
// eslint-disable-next-line no-nested-ternary
isUserLogged || isAuthenticated ? (
<Component {...props} />
) : isLoading ? (
<Spin size="large" />
) : (
<Redirect
to={{
pathname: '/login',
}}
/>
)
}
/>
);
}
